Global coronavirus cases exceeded 10 million on Sunday, according to a Reuters tally, marking a major milestone in the spread of the respiratory disease that has so far killed almost half a million people in seven months.

The figure is roughly double the number of severe influenza illnesses recorded annually, according to the World Health Organization.

The milestone comes as many hard-hit countries are easing lockdowns while making extensive alterations to work and social life that could last for a year or more until a vaccine is available.
